Impact
By pushing GPT-5.5 Instant to frontier-level performance on health questions and backing it with a large global physician network, OpenAI is positioning ChatGPT more firmly as a first-line health information resource. This strategy could accelerate AI’s role in triage and basic guidance, while intensifying scrutiny from regulators and healthcare incumbents over safety, liability, and clinical validation.
